METAL-POLISH.

Specification of Letters Patent.

Patented April 21, 1908.

Application filed May 7, 1907. Serial No. 372,308.

of Connecticut, have invented certain new and useful Improvements in Metal-Polishes; and I do hereby declare the following to be a full, clear, and exact descri tion of the invention, such as will enable O'SXEIS skilled in the art to which it appertains to make and use same.

This invention relates to new and useful improvements in metal polishes and the object of the invention is to produce a polish having properties which render the same firedestroying the efficiency of the material as a polish.

| My metal polish comprises the following ingredients: to four gallons of naphtha are added three and a half gallons of carbon tetra ehlorid,-six pounds of red oil or stearic acid,

two pounds of aqua ammonia of 26 degrees.

as an alkali which are thoroughly stirred in a steam mixer and, when all of the 'parts are thoroughly mixed, the material is of the con- 30 sistency of a finished soft soap, after which nineteen pounds of silica are added thereto and agitated in a steam mixer.

By the employment of more or less of the naphtha and carbon tetra chlorid acting as a solvent, my metal polish may be reduced to any desired consistency either as a paste or,

5 by adding more of the solvent, may be thinned and to the mixture maybe added any other scouring material in place of the silica, such as tripoli, powdered stone or whitening.

tially the parts set forth, is put into a mixer and thoroughly mixed.

Metal polishes have been heretofore more i or less unsatisfactory requiring much labor and time and apt to lire at a low temperature, whereas my composition produces a liquid or paste polish as roportions are varied, which will produce a rilliant surfacein less time and with less labor than polishes heretofore employed and, at the same time, be uninflammable at any atmospheric temperature and, by increasing the quantity of the noninfiammable solvent, the composition will act as a fire extinguisher.

I have found that, when the ingredients are compounded in the manner set forth, the composition will be of such a consistency that none of the ingredients will settle to such an extent as to harden upon the bottom of areceptacle in which thematerial is stored.

What I claim to be new is A non-inflammable liquid polish consisting of ammonium oleate, aqua ammonia, silica, naphtha, and carbon tetra chlorid in the proportions herein set forth.

In testimony whereof I hereunto aflix my signature in the resence of two witnesses.
